Applieation filed March as, 1921. Serial No. 455,812.

To aZZ whom it may concern:

Be it known that I, CHARLES HowAno STAMM, a citizen of the United States, re-

siding at Indianapolis, in the, county of Marion and State of Indiana, have invented a new and useful Dimmer for Automobile Headlights, of which the following is a specification.

This invention relates to a combined shade and dimmer for automobile headlights, one

of its objects being to provide a device of this character which can be applied readily to an automobile and which, when in position, can be actuated so as to deflect the light the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a plan view showing the device in position.

. Figure 2 is a section on line 22, Figure 1, the lamp being shown in elevation.

Figure 3 is a front elevation of one lamp equipped with this improvement.

Figure 4- is a plan View of the sheave carrying bracket.

Figure 5 is a detail view of the chain hold in; bracket.

Referring to the figures by characters of reference A designates the radiator, B the hood and C the radiator cap of an automo bile, the usual lamps D being mounted in front of the radiator at the sides thereof within suitable supports E, as shown.

The present improvement includes a split ring 1 made up of members hingedly connected as indicated at 2, the free ends of the ring being outturned to provide ears 3 adapted. to

' What is claimed is be engaged by a bolt 4 whereby the ring can be apphed to the rim of a lamp and fastened thereto securely by tightening the bolt. This ring has oppositely extending pivot'lugs or pro ections 5 on which is pivotally mounted a transversely arched hood.6. Springs 7 are connected to the sides'of the hood and to. the 1 ring and serve to pull the front portion of the hood downwardly'so as to partly cover the lens of the lamp. An inwardly turned flange 8 is provided at the back of the hoodv and is designedtoengage the top portionof the lamp, thus to limit the, upward swinging ofthehood.

Connected to the front portion of the hood 6 is a flexible actuating device which can'be in the form ofa chain 9 extending over a' guide sheave 10. This guide sheave is preferably mounted withina bracket 11 having Y a recessed portion 12 adapted to straddle the fillin neck of the radiator A below the cap 0. yoke 13 is adapted to be fastened to the bracket'so as to cooperate therewith for holding the bracket to the neck ofthe radiv ator thus to maintain the sheave 10 in proper position. From this sheave the actuating device '9 can be extended back under the hood B and thence to a bracket 14 mounted on the dash-board of the vehicle, this bracket being provided with a fork 15 through-which the connection 9 can extend. For-the purpose of holding the connectionin engageweight can be connected to the free end of the part 9 as, shown in Figure 5. lVith the chain in engagement with this bracket 14 the hood -6 cannot swing downwardly. By disengaging the chain from the bracket 14,

however, the springs 7 will operate to swing ment with the forka ball 16 or other small it as would be the case should this-bar 17 not i be employed. 1

comprisdriver for tilting said hood against the tension of said springs. v

In testimony that I claim the foregoing as my own, I have hereto afiiXed my signature in the presence of two Witnesses.
